Ingredients Label

Active Ingredients

PeakO2 Blend

PeakO2 is a blend of mushroom extracts, which have been shown to improve power output and time to exhaustion (1).

The main ingredient, cordyceps, has a long history of use in medicine and performance enhancement, most prominently in Chinese medicine.

Tyrosine

Tyrosine is a stress-reducing amino acid.

It lowers stress hormones resulting in improved performance in those who are fatigued or otherwise stressed (2).

The effective dose is 500-2,000mg.

Choline

Choline is brain-boosting vitamin (3).

This formula contains two forms of choline: Choline bitartrate, and Alpha-GPC.

Bitartrate is a relatively cheap form, which isn’t well absorbed. Alpha-GPC, on the other hand, is an active form which improves memory, focus, and even power output (4).

Nitric Oxide Boosters

Citrulline malate, arginine, and agmatine are all nitric-oxide boosting compounds (5, 6, 7).

Increasing nitric oxide levels can enhance vasodilation – a widening of the blood vessels. This results in improved blood flow, endurance, and more pronounced pumps while lifting.

Taurine

Taurine is a cell-volumising amino acid.

It regulates the size of muscle cells – enhancing your pumps in a different way to nitric oxide.

The effective dose is about 1g.

L-Ornithine

L-ornithine is an amino acid which has been shown to reduce fatigue (8).

An effective dose is about 2g.

Glycerol

Glycerol is a sugar-alcohol, which improves pumps by acting as a plasma-expander, increasing the total volume of blood in the body (9).

Amentoflavone

Amentoflavone is a vasorelaxation agent, making it yet another ingredient that temporarily increases blood vessel size (10).

Who Takes It?

Athletes wanting a pre-workout that will increase their pumps and endurance levels will enjoy using rhino Black Series Pumped.

How to Take

Mix either one-half or one full scoop 250mL water, and consume 30 minutes before working out.

Side Effects

May upset the stomach if taken without sufficient water or food.

Pros

• Uses a range of mechanisms to improve pumps during workouts
• Also improves performance and focus
• Ingredients added to improve absorption.

Cons

• No stimulants, and lacks key performance-enhancing ingredients.

Conclusion

Rhino Black Series Pumped is a stimulant-free pre-workout formula which focuses almost exclusively on improving pumps.

It does this well, using a whole range of pump-inducing ingredients at effective doses, which work synergistically to deliver the best results possible.

Although it lacks somewhat in boosting energy and performance, it is designed to be easily added to a stimulant-containing pre-workout of your choice.
